Thickness of Seal Ring
1. Measure the thickness of seal rings (1) with an outside
micrometer.
2. If the measurement is less than the allowable limit, replace it.

(D) Differential Gears
Spiral Bevel Gear Turning Torque
• It is necessary to adjust the spiral bevel gear turning torque,
when replacing the differential gears, transmission case or
other relative parts.
1. Assemble the differential gears to transmission case. At this
time, install the some shims (3) to the spiral bevel gear side.
2. Check the turning torque by using turning torque tool (1).
Turning Torque Tool : Weld socket on the brake shaft
(Brake shaft Part No. TA040-26710)
3. Add or reduce the thickness of shims (3) to make the specified
turning torque.
4. After getting the specified turning torque, divide the thickness of
shims to left and right side.
5. Assemble the transmission case and adjust the backlash and
tooth contact with spiral bevel pinion. (See next page.)
